The fuel reservoirs currently used with the IQT™ must be filled when they are mounted on the IQT™'s fuel injection pump. This requires the IQT™'s operator to handle potentially volatile fuels such as heptane and MEH without the increased protection provided by a fume hood or well ventilated area. Fuel spillage on the LM-IQT™ would tend to remain until cleaned; which can allow operators to be unnecessarily exposed to fuel vapours.

The new self-sealing fuel reservoirs have a small ball check valve in the bottom of the reservoir and come with a cleaning/filling station. This allows them to be filled in a safe, fume hood or other ventilated area, and then transferred to the IQT™ for testing.
